@cptken You’re blowing this week’s assignment out of the water 💥
Individually detailed fingers and toes…that takes tiiiime. And everything is looking very nice. Brilliant work, my dude!
It sounds like you might be maxing out dynamic topology’s workability. Once your into a few the millions of polys, dyntopo gets impractically slow. And it sounds like you want to add more details. Granted you’re way beyond the scope of this week’s assignment so my next suggestion is not required, but if you want to keep going with the orc, I’d recommend converting over to multires.
First do an optimized retopology then use the technique in this video to salvage all your detail in a multi-res modifier. From there you can subdivide into much higher polygon counts with multi-res.
